Question

y = 5x + 4
y = 5x - 3
a. no solutions
b. (0,4)
c. infinitely many solutions
d. (0,-3)

Answer 1

both of those lines have a slope of 5. when two lines have the same slope, they're parallel. knowing that they're parallel, what's our answer?

Answer 2

c?

Answer 3

no. c can only be the answer if our two lines had both the same slope and y-intercept. our answer is going to be a

Answer 4

i see what youre saying about that one now.
i need help with another one.

Answer 5

y = -5x - 2
y + 2 = -5x
a. infinitely many solutions
b. no solutions
c. (0,-2)
d. (0,2)

Answer 6

we want to convert the second equation into slope-intercept form: y = mx + b. can you do that?
